<blink>Error:</blink> Marvin cannot load a module, a template or a molecule file
</font>

<p>
One of the following two possibilities might have caused the problem:
<ul>
<li>The file and Marvin are not on the same server.
    From security reasons, Java applets can only access files from their host
    web site.</li>
<li>You are behind a <i>firewall</i> which does not proxy DNS correctly or
at all. Netscape Navigator 4.01 and later versions do not trust in such
misconfigured proxies by default, so applets cannot connect back to their host
web site.</li>
</ul>

<center><div class="lenia">&nbsp;</div></center>

<p>There are two ways to solve the <b>firewall</b> problem:
<p>
<i>1.</i>
    Ask the system administrator of your intranet to reconfigure the firewall
    correctly, or
<p>
<i>2.</i>
Modify Netscape's preferences &quot;manually&quot; by editing your
Preferences file.<p>
The name and location of this file varies from platform to platform: 
<blockquote>
<table CELLSPACING=10 CELLPADDING=0 BORDER=0>
<tr ALIGN=LEFT>
    <td>Macintosh:</td>
    <td>System Folder:Preferences:Netscape f:Netscape Preferences</td></tr>
<tr ALIGN=LEFT>
    <td>UNIX:</td>
    <td>~/.netscape/preferences.js</td></tr>
<tr ALIGN=LEFT>
    <td>Windows:</td>
    <td>\Program Files\Netscape\Users\&lt;username&gt;\prefs.js</td></tr>
</table>
</blockquote>
Be sure to edit this file only while all instances of Netscape are shut down,
as Netscape will overwrite the file when it exits. 
<p>
To enable the preference, add this line to the Preferences file:<br>
<pre>
user_pref("security.lower_java_network_security_by_trusting_proxies",true);
</pre>
